formaggio writes: Researchers at MIT recently announced plans to create a “solar energy funnel” that could harvest energy from a much broader spectrum of sunlight than silicon photovoltaics are currently able to achieve. Ju Li, an MIT professor, and Xiaoteng Qian, a postdoc student, published a paper this week in Nature Photonics describing the funnel, which is made from a vanishingly thin material called Molybdenum Disulfide (MoS2).
